Biological Activity
The formation of Coenzyme FO is mediated by two separate radical SAM active sites, one each in the CofG and CofH enzymes or both in the FbiC enzyme. These two radical SAM domains constitute the functional domains of Fo synthase. F420 is biosynthesized in Methanocaldococcus jannaschii by the action of eight enzymes with the formation of the deazaflavin chromophore (Fo) as the remaining unsolved step[1].
Coenzyme F420 is the central low-redox-potential electron carrier in methanogenic metabolism. Coenzyme F420 is reduced under hydrogen by the action of F420-dependent hydrogenase[3].
Coenzyme F420 acts as a hydride transfer coenzyme for an F420-specific glucose-6-phosphate dehydrogenase (Fgd) in mycobacteria. Coenzyme F420 is found in all methanogenic and certain nonmethanogenic archaea, where it participates in energy metabolism, NADP reduction, oxygen detoxification, and sulfite reduction. By converting NO2 back to NO with F420H2, M. tuberculosis could decrease the effectiveness of antibacterial action of macrophages[4].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 1 mg/mL (2.75 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 1 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 0.53 mg/mL (1.46 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 0.53 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.3 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
